BINDING STRIP Filed April 29, 1929 mm G. Woodman Patented July 8, 1930UNITED STATES ALBERT G. WOOD'MAN, OF GRAND BAP-IDS, MICHIGAN BINDINGsemi Application filed April 29,

This invention relates to a binding strip of metal which, in use, isadapted to be placed around a base member having corners, the bindingstrip being bent at the corner to fit the base. There are many relationsin which this binding strip may be used and in practice I have used thesame to bind and connect the fabric member of a bee-smoker bellows toopposed bases though it is to vbe understood that the binding strip isadapted for use in many other places.

Binding strips of this character are ordinarily formed with an inturnedflange at one edge and my invention is primarily concerned with a novelconstruction whereby the strip with the integral flange may be readilybent at the places necessary to conform the strip around the corners ofthe member to which it is to be secured. And I have attained this resultin a relatively simple but very practi cal and satisfactory manner aswill be apparent from the following description of the invention takenin connection with the accompanying drawing, in which,

Fig. 1 is a perspective view showing the binding strip located aroundand secured to a base member.

Fig. 2 is a fragmentary enlarged perspective view illustrating onecorner portion of the strip.

construction shown in Fig. 3.

Like reference characters refer to like parts in the different figuresof the drawing.

The binding strip 1 of flat metal is of a length to pass entirelyaroundthe base memher to which :it is to be secured. The strip at one edge isformed with an inwardly turned flange 2 located at an angle to the planeof the body of the strip and when the strip is placed around andattached to a base member, as 3, the edges of the flanges 2 bear againsta side of said member.

The strip at the places where it is to. turn the corners around the basemember is pressed inwardly at the flange portions thereof formingrounded beads 4 which are shaped so that 'beads4 curled or dented in atthe corners this character. Cutting away portions of the Fig. 4 is afragmentary plan view of the g at any portion. Moreover, the cornersmade 1929. serial No. 358,851.

the sides are parall'elto the sectionof the binding strip 1 at each sideof a corner, thereby permitting the strip to be readily bent at saldcorner withoutbuckling-of the metal or distortion thereof in anyrespect. The bind- :5,

ing strip is formed with as many of the beads 4'in the flanges 2 asthere are corners tobe turned about the base member and the beads 4 arepositioned proper distances apart so that the same comeexactly at thecorners of the base member. I

The strip is provided with a plurality of openings in its length throughwhich nails 5' or similar fastening devices may be driven into the basemember when the strip is ap- "c5 plied thereto. The ends of the stripoverlap and there is but one joint in the strip around the entire base.2

With this construction of binding strip the permits the binding strip topass around the corners without cutting away any portion of the flanges2 as has beenthe usual practice at the corners heretofore with bindingstrips of flanges where the strip is bent around the corners of the baseleaves edges, sometimes rough and sharp, which are disadvantageous in adevice of this character, while the strip with the integral curved beadsinthe flanges at the corners thereof are smooth and unbroken and do notpresent any rough or sharp edges. The flanges 2 form a surrounding beadwhich presents a smooth and rounded outer edge to the strip, and withthe binding strip as made in accordance with this invention all portionsof. the strip which may be contacted against are smooth withoutroughened or sharp edges are of considerably greater strength andrigidity than when parts of. the flanges 2 are cut awayto permit readybending. The construction while of relatively simple character is one ofmerit and has proved its worth in actual practice. The invention isdefined in the appended claims and is to be considered comprehensive ofall forms of structure coming within the scope of the claims.

I claim:

1. In a construction of the class described, a base member havingcorners, a binding strip of flat metal located around said base membercomprising a continuous length of flat metal formed at one longitudinaledge with a return bent flange located at an angle to the body of saidstrip, the edge of said flange bearing against a side of the basemember, and said flange at the corners of said base member being pressedtoward the body of the binding strip into beads continuous with theflange.

2. In a construction of the class described, a rectangular base member,a binding strip surrounding said base member comprising a continuouslength of flat metal having a flange at a longitudinal edge thereof bentback toward the base member at an angle to the body of the bindingstrip, and beads in said flange pressed toward the body of the bindingstrip at the corners of the base memher.

3. In a construction of the class described, a base member, a bindingstrip of flat metal around said base member formed with a flange at onelongitudinal edge bent back toward and engaging against the base member,said flange at the corners of the base member being continuous andformed into shape to permit the ready turning of the corners of saidbase member by the binding strip.

In testimony whereof I afiix my signature.

ALBERT G. WOODMAN.
